Abstract

A domestic central heating system has a flat radiator attached to the wall by mounting brackets (1). Each wall bracket has a lower section (2) with a channel profile which receives a matching slide-fit upper section (4) with clamp (20). The upper section is esp. infinitely height-adjustable within the given range of movement.

Description

The invention relates to a holding device, in particular for panel radiators, consisting of a stationary wall bracket and a holding bracket movable relative to the wall bracket, wherein the wall bracket has at least one lower fixed receiving element for the radiator and the height-adjustable holding bracket is accommodated in the opposite end of the wall bracket.

Holding devices are required for the installation of radiators, particularly panel radiators, which hold the radiator in a desired position on the wall. The holding device is screwed to a wall and then enables the panel radiator to be hung in a vertical position. After the panel radiator has been hung, the radiator is aligned and secured vertically using a clamping screw or other mechanical elements. The clamping screws or mechanical elements can be attached directly to the wall or be part of the already installed holding device. The clamping screws or other mechanical elements used are arranged according to the specified panel radiator size and must be adapted in the event of a replacement, particularly if the panel radiator size is different, which is complex and costly.

To make it easier to install different panel radiators, it is therefore suggested, for example, that a holding bracket with a fastening bracket encloses the panel radiator in the upper area, with the holding bracket being inserted in locking steps so that it can be moved axially relative to the wall bracket. Due to existing component tolerances, the use of locking steps means that the radiator is not clamped sufficiently and it may not be sufficiently secured in the upper area and have too much play.

The invention is based on the object of creating a holding device which, on the one hand, can be produced cost-effectively and, on the other hand, enables flexible adaptation to possible construction tolerances of the panel radiators.

According to the invention, to achieve the object, the holding bracket has a clamping element that can be continuously adjusted in the respective height, which consists of a cuboid-shaped base body that can be inserted into the wall bracket and has at least one molded elastic leg, and has a locking element mounted in the base body and the at least one leg, which protrudes from two lateral openings in the base body. Further advantageous embodiments can be found in the subclaims.

Due to the infinitely adjustable nature of the upper holding bracket, existing construction tolerances can be compensated for very easily in the object according to the invention, since the holding bracket is infinitely adjustable and thus ensures that the panel radiators are securely fastened without play. The presence of a locking element makes it possible to press down the holding bracket while simultaneously inserting the clamping element into the wall bracket, but prevents the holding bracket from coming loose or being accidentally pulled out of the wall bracket. If the holding bracket is to be released, the locking element can be moved from a locking or blocking position to a release position by at least one movable elastic leg. Preferably, two spring-elastic legs are used here, which are formed on the base body and enable the locking element to be unlocked from the wall bracket when pressed together. At the same time as the two legs are pressed together, they can be used to pull the holding bracket out of the wall bracket so that the radiator is released.

For this purpose, the leg ends, which are molded onto the base body, protrude upwards from the wall bracket and have a one-piece molded pressure surface that extends beyond the width of the leg or can, for example, be angled and have a one-piece molded pressure surface, so that the fitter can easily press both leg ends together.

In order to ensure that the locking element provides sufficient resistance against unintentional pulling out of the retaining bracket, the locking element consists of an arc-shaped spring steel, the end faces of which are made of the

&igr; :

protrude from the existing openings in the base body and are in contact with the inner surfaces of the wall bracket.

In addition, in a special embodiment of the invention, the base body has a recess for mounting the locking element, with a pin being formed in the recess, on which the locking element rests with an outer surface to provide support. This ensures that the locking element is prevented from slipping or giving way. In such a case, the frictional contact of the end faces with the inner wall of the wall bracket would otherwise no longer be sufficient and would cause the holding bracket to slide out of the wall bracket. However, the pin prevents the spring steel from giving way and at the same time has a stabilizing effect on the spring steel, so that the end faces generate a high pressure force. Alternatively, there is the possibility of an additional bearing pin being formed on the pin, on which the locking element rests with a corresponding bearing surface, for example a semicircular recess. This measure ensures that the locking element is mounted centrally in the base body and cannot protrude from the opening on one side or the other. The acting forces are thus evenly transferred to the two parallel inner sides of the wall bracket and the pin also prevents the shaped locking element made of spring steel from bending.

Preferably, the arc of the locking element lies within the base body in the direction of insertion and the front surfaces come into contact with the inner walls of the wall bracket through the existing openings in the base body. Only by pressing the leg ends together is the locking element released from the inner walls and the holding bracket can be pulled upwards out of the wall bracket to release the radiator. For better guidance and increased sliding ability, the cuboid-shaped base body is made of plastic and is further reinforced by a guide plate. The guide plate preferably has a rectangular opening through which two holding claws of the base body engage for fastening and locking, thus creating a compact component that can be pre-assembled as an accessory or spare part for replacement and can also be used particularly easily on site thanks to the pre-assembly.

••&iacgr;.

Pre-assembly means that there is no need to assemble the individual parts on site and potentially lose or damage them. The base body with locking element and guide plate is pre-assembled and can be pushed into the wall bracket from above and can be adapted to the size of the radiator in different versions if necessary. In order to hold the bracket captive in the angle profile, the base body is equipped with a nose which is integrally formed and protrudes from one side surface and, after assembly, snaps into a slot in the angle profile, with the nose having a bevel for pressing in in the direction of movement towards the angle profile.

The support bracket consists of a base body that can be moved continuously in the wall bracket and a clamp bracket that spans the radiator, whereby the clamp bracket is attached so that it can be moved relative to the base body, for example by means of a screw bolt. This makes it possible to align the radiator vertically after partial assembly and to ensure sufficient fastening by simultaneously pressing down the continuously adjustable support bracket.

To accommodate the radiators, which can have different material thicknesses and plate thicknesses, the lower end of the fixed receiving element of the wall bracket has several recesses adapted to the radiator, preferably with sawtooth-shaped depressions, which largely correspond to the rib shape or bend or flanging of the common radiator types, whereby the receiving bracket can be designed to be replaceable by means of a plug-in device if necessary.

In order to prevent the elastic legs from being accidentally compressed, a locking element can be inserted between the elastically formed legs and screwed together with the clamping bracket if necessary, so that the holding bracket can only be pulled out upwards by pressing the two legs together after loosening the screw connection.

The invention is explained in more detail with reference to the figures.

Figure 1 shows a perspective side view of a holding device 1 in a front and rear view, consisting of a screw-on L-shaped angle profile 2 as a wall bracket, a receiving element 3 for a radiator (not shown), and a height-adjustable holding bracket 4 with an insertable base body 5. The angle profile 2 has a U-shaped cross-section, with the tapering legs 6, 7 in the upper area partially having a right-angled, inward-facing bevel 8. The bevel 8 rests with its flat side on the base body 5 and serves to guide it within the wall bracket. The angle profile 2 is straight in the upper area, while in the lower area an angle profile end 9 bent by approx. 60 to 90 degrees is provided for fastening the receiving element 3. The formed legs 6, 7 run from the upper end of the angle profile 2 into the angle profile end 9 in order to achieve sufficient stiffening of the wall bracket, whereby the legs 6, 7 decrease in width towards the angle profile end 9. The receiving element 3 is attached to the bent angle profile 9, which has several sawtooth-shaped recesses 11 and merges into a raised projection 12 in the front area so that the inserted radiator cannot slip off. The radiator (not shown) can be inserted into the existing sawtooth-shaped recesses 11 or depression and thus enables an immovable

In a further embodiment of the invention, the receiving element 3 can be designed to be exchangeable and can have different dimensions and recesses depending on the shape of the radiator to be attached.

To fasten the receiving element 3, there is an opening in the angle profile 2 in the area of the lower angle profile end 9 through which the holding claws 10 of the receiving element 3 reach and lock it to the angle profile 2. The receiving element 3 can be removed at any time by pressing the holding claws 10 together.

The angle profile 2 also has an elongated hole 13 and an opening 15, which transitions from a longitudinal slot 16 into an enlarged opening 17. The elongated hole 13 and the longitudinal slot 16 are intended, for example, for fastening the angle profile 2 to a wall, with fastening bolts (not shown) engaging through the elongated hole 13 and the longitudinal slot 15 into existing dowel holes. The opening 15 with the longitudinal slot 16 and enlarged opening area 17 can also be used to accommodate any additional aids that may be required to stabilize the radiator. Above the opening 15 there is also an elongated hole 14, which is intended for locking the holding bracket 4. To lock the retaining bracket 4 in the angle profile 2, a nose 45 is provided which is formed on the base body 5 and protrudes outwards. This nose is partially rounded and bevelled so that the retaining bracket 4 can be inserted into the angle profile 2 from above and the nose 45 is initially pushed back until it spring-loadedly engages in the slot 14. The retaining bracket 4 can only be completely removed if the nose 54 is pushed inwards. Both parts are thus connected to one another in a captive manner.

The holding device 1 can be delivered in two parts, whereby, for example, the radiator is delivered with a matching holding bracket 4 and the holding bracket 4 only needs to be subsequently inserted into an existing or separately supplied wall bracket or angle profile 2. By delivering in two separate parts, the desired combination can be put together at the factory at the last moment. This can, for example, reduce storage and lead to savings in storage space and costs.

The holding bracket 4 consists of a continuously insertable base body 5, which is guided between the legs 6, 7 of the angle profile 2 and is equipped with a guide plate 18 for reinforcement and a clamping bracket 19 with a molded, replaceable hook 20 for gripping the upper end of the radiator. The base body 5 is connected to the guide plate 18 via two integrally molded, oppositely aligned holding claws 21, 22, with the holding claws 21, 22 gripping behind the guide plate 18 through an opening 23. The holding bracket 4 can therefore be completely pre-assembled without the individual parts falling apart.

The guide plate 18 also has an angled leg 24 at the upward end, which has a threaded hole 25 for receiving a screw bolt 31. To guide the clamping bracket 19, the leg 24 is slightly bent on both sides, so that a corresponding bevel 26 of the clamping bracket 19 is guided on it. Between the clamping bracket 19 and the guide plate 18, a locking element 27 can also be placed on the upper leg 24, which is designed in an arc shape with two tapering legs 28, 29 that form a right angle to each other, with a through hole 30 in the upper leg 29, through which the screw bolt 31 can engage in the threaded hole 25 of the guide plate 18. After assembly, the leg 28 comes to lie between the inner sides of the elastically formed legs 32 of the base body 5 and thus prevents compression. The clamping bracket 19 has an elongated hole 33 for receiving the screw bolt 31, which is arranged corresponding to the through hole 30 or the threaded hole 25. The holding bracket 4 can be equipped with several different clamping brackets 19, for example for vertical radiators, covered or uncovered radiators.

The holding bracket 4 is shown in Figure 2 with its individual parts before assembly and in Figure 3 after assembly in a perspective view.

The base body 5 is, as already stated, reinforced by the guide plate 18 and has a semicircular

recess 35 with slanting lateral openings 36, 37. In the middle of the recess 35, a pin 38 is formed in one piece, which has a bearing pin 39 on one side, on which the arched locking element 34 made of spring steel rests with a recess 40. The recess 40 is formed in a right-angled leg 41, which at the same time ensures lateral guidance of the locking element 34 relative to the pin 38 within the base body 5. The two front ends 42, 43 of the locking element 34 protrude from the lateral openings 36, 37 of the base body and, after assembly, partially rest on the upper or lower surface of the openings 36, 37, so that when the two legs 32 are pressed together, the locking elements 34 bend slightly inwards, whereby the front ends 42, 43 are simultaneously lifted off the inner walls of the angle profile 2 or the leg surfaces and enable the entire holding bracket 4 to be pulled out upwards.

To limit the insertion of the base body 5 into the wall bracket, the protruding ends of the legs 32 are formed at right angles and thus lie directly on the upper edge of the angle profile 2 in the lowest position. At the same time, the formed pressure surfaces 44 ensure that the two legs 32 are pressed together at all times, unless the locking element 27 is mounted between the legs 32.

Figure 3 shows the completely pre-assembled holding bracket 4 with base body 5, guide plate 18, locking element 27 and screwed-on clamping element 19. From the perspective view, it is very clearly visible how the locking element 34 lies in the existing recess 35 of the base body 5 and protrudes with its lateral end faces 42, 43 from the existing openings 36, 37. If the holding bracket 4 is pushed into the upper end of the angle profile 2, the end faces 42, 43 of the locking element 34 come to rest on the inner surfaces of the legs 6, 7 and are slightly pressed together inwards. However, because it is a spring steel band, a corresponding counterforce is generated, which ensures sufficient friction between the end faces 42, 43 and the legs 6, 7, so that in the event of an attempt to pull it out without pressing the two legs 31, 32 together, there is sufficient resistance to block the holding bracket 4. Only when the two legs 31, 32 are pressed together is the contact between the end faces 42, 43 and the inner surfaces of the legs 6, 7 removed and the holding bracket 4 can be pulled out after

above. This makes it possible to attach the radiator to be mounted quickly and easily, taking into account the respective radiator height, and to remove it again for dismantling.
